The headlight blew on my TY175 so I ordered a 6 volt 25W/25W replacement. However the shop have sent me a 6 volt 35W/35W bulb. According to my calculations the 25W bulb uses 4 amps and the 35W bulb uses 6 amps. My Haynes manual says the unregulated AC circuit relies on the correct wattage bulbs being used. Has anyone else used 35W bulbs? Is it that critical?

Had a look at the chain tensioner last night with a view to ordering a new spring and block, but it seems it's in worse condition than I thought, the sleeve part of the tensioner that goes over the stud on the swing arm is all worn away on the one side and ovalled out. I might be able to find a second hand replacement on eBay, but does anyone know if there are any alternatives available? There seem to be after market versions (smp) for the 125 & 175, but not the 250. Are they much different? I noticed the spring is actually the same for all models. Any advice or help welcome! Cheers

Hi, I need a shifter drum for my 1978 ty 175 and would like to install the ty250 piston in my overbored cylinder to up the displacement to 192cc. Please advise which 250 piston I need, pre-mono or? Cheers, Guy

I need to use a TY 250 twinshock I have not used for a few years and cannot find or remember some simple information What volume and specification of oil do I use for the front forks and the gearbox/clutch? Thanks

I have just bought a 1977 Ty 125 off Swiss e-bay (Ricardo). It is very tidy but totally gutless! Are there any quick fixes that can be done at home to liberate a few extra horses? I wonder if it was maybe restricted for use as a learner bike?

I have an oil leak from the gear selector shaft, is this easily fixed? Is it just a case of pulling out an oil seal and replacing, or will the gearbox need to be stripped. Any advice appreciated, many thanks in advance.

Does anybody know whether those little 12 volt tyre inflators on e bay for

I have a 44(H) 1984 TY250(L) and I am going through some confusion with spark plugs and resistor caps. The manual says (yes I have the original manual) use Champion N5G - most cross references map this to NGK B6EV. However on http://www.yamahaty.com/english/bougiesen.html he maps the Champion N5G to B6EVX (high performance - no resistor). Any mono owners out there - what plug do you run? The previous owner was running BR6ES with a plug cap that has a resistor in it as well. Does the resistor really make a difference? The only thing it does is reduce noise - does it interfere with the CDI? thanks

Currently restoring my Yamaha TY 175. Planning on having all the alloy / magnesium aqua blasted i.e. crankcases, yokes, brake plates etc. Ive been told this gets a very nice finish. Has anybody done it ? Maldon seems to be a reputable company. Has anybody used them ? Also has anybody done it to their carb ? Surely if all the jets are removed and you flush it through with compressed air and solvent it should be ok. People have told me not to do it. Shame to spend all that time restoring a bike just t have a manky old carb sitting in the middle of the bike.

Does anyone have the length of the spacer required when removing the speedo on a drum brake mono? Thanks

It would appear I didn't post the successful rebuild of our TY80 engine after some problems discovered, so here it is: Just to recap, a year ago we acquired a TY80 that had a recent rebuild but suffered from a gear-change problem – up changes fine but down changes very unreliable. It also rattled more than I would have expected from a rebuilt engine… So easy job first and check the clutch mechanism and general condition under the LH case: All good, so take off the RH case and clutch to check the gear-change mechanism: Note the fantastic homemade clutch holding tool that came with the bike. The gear-change mechanism has nothing obviously wrong but I notice the …

Well my rebuild of this little motor is done and back in the frame. It starts first kick and has a good spark but Boggs down in neutral when I twist the throttle. adding choke helps a lot but still Boggs when out under the slightest load. once warm it will bog down with or without choke on acceleration. ill change the fuel tomorrow and maybe check the plug, maybe pull the carb and check float height and jets any other ideas welcome please thsnks ron
